Miklos Szeredi 7d9f345ca6 9p: use file_dentry() ... commit b403f0e37a11f84f7ceaf40b0075499e5bcfd220 upstream. v9fs may be used as lower layer of overlayfs and accessing f_path.dentry can lead to a crash. In this case it's a NULL pointer dereference in p9_fid_create(). Fix by replacing direct access of file->f_path.dentry with the file_dentry() accessor, which will always return a native object.
